  • Patent number: 9380405
    Abstract: The disclosure discloses a method for triggering a Machine Type Communication (MTC) device, where an SGSN/MME receives a trigger from an MTC-IWF, and determines that the MTC device is in an unattached state and the MTC device is in a communication window of the MTC device; when the MTC device gets attached to the network before expiration of the communication window, the SGSN/MME sends the trigger to the MTC device; or when the MTC device fails to get attached to the network before expiration of the communication window, the SGSN/MME sends a trigger transmission report to the MTC-IWF, such that the MTC-IWF saves the trigger by sending the trigger to an SMS-SC, and forwards the trigger transmission report to an MTC server initiating the trigger. The disclosure further discloses a system for triggering an MTC device corresponding to the method. With the disclosure, an MTC device in an unattached state can be triggered.
